These days, in the use of NAF 9.8.6. We found that the juniper equipment and the flow of the actual flow gap, only the actual flow rate of 1/10, or even less. Do not know what method can solve this problem, the following is our equipment configuration.

forwarding-options {
    sampling {
        input {
            rate 100;
            run-length 9;
            max-packets-per-second 7000;
        }
        family inet {
            output {
                flow-server 192.168.21.112 {
                    port 9996;
                    no-local-dump;
                    version 5;
